Yugioh 5Ds has always revolved around people known as Signers. There are five Signers, one of which is unknown. Rex Goodman, tries to bring the Signers together in order to summon the Crimson Dragon Each Signer has a dragon and later in the story, they fight Dark Signers, duelists who try to revive the Grand Earthbound God. Now as I looked around the web, everyone was wondering who was the final Signer? I donâ€™t have an answer but I might be able to give a guess.
Many people thought that Rex Goodman was the fifth Signer, however that cannot be true because when Akiza and Yussei summon Black Rose Dragon and Stardust Dragon, every Signersâ€™ arm starts glowing except Goodwinâ€™s. Plus when he showed his metal hand to Jack, there was no mark. If Goodwin was the last Signer he would immediately have a meeting with all the other Signers.
I thought the last Signer was Sayer, the leader of the Arcadian Movement, because he was always appearing in the scenes. Plus, I thought that he put Akiza in the tournament to find the other four Signers. However if he was the fifth Signer, than Akiza and Goodwin would have known and they would both say something to him. Sayer also lost his life when he lost a shadow duel against the Dark Signer, Carly. Important people of the plot such as Signerâ€™s donâ€™t just die like that.
My best guess for who the fifth Signer is Crow, because he has the same personality as Yusei and he also has a powerful dragon monster in this deck. Crow also looks like Singner material. However I may be wrong but it is still a fun mystery, who really is the fifth Signer?
